Let me state at the outset: I am not saying that DLT (Distributed Ledger Technology) itself is coming to an end. On the contrary, distributed ledger technology will become the mainstream from here on out. I am asserting that the mainnets of so-called “blockchains” currently dominant in 2024—those that only handle approval processing in a strictly serial manner—along with the smart contracts operating on them and the exchange of numbers called “tokens” that follow certain specifications, will all eventually perish.

To cut to the conclusion first: Directed Acyclic Graphs (DAGs)—especially Hashgraphs—represent the DLT model that will be chosen as the next generation’s accounting technology, because they enable parallel and concurrent processing of approvals. “Hedera Hashgraph” is what realizes this.

Mathematically speaking, the old-style blockchain was correct, but it could not handle micropayments, rapid decision-making, or incorporate human-like qualities. At best, consensus methods like PoS or PoH using a committee structure were just a little faster. The rising electricity costs and environmental pollution caused by PoW, combined with its slow processing, were more than enough to disillusion people.

In today’s Web3 world, all sorts of projects called Layer 2 or “off-chain,” or some “blockchain-like” systems scientifically concocted by a certain professor, proudly claim to be n times faster, cheaper, and more performant than Ethereum, and they’ve made slick landing pages to say so. Comparing things to Bitcoin or Ethereum is like comparing an ox cart to a modern automobile. Their purposes are entirely different to begin with.

However, all these conflicts will soon vanish. And those chains will be abandoned by people, leaving behind only a cluster of servers destroyed by Sybil attacks. It’s easy to foresee that they’ll become worthless trash that’s just a bit faster than their predecessors. Any cross-chain products that connect them will likewise become useless.

In the first place, do you really think that blockchain networks can adapt, update, or upgrade themselves to be compatible with Hashgraph? Can you attach an engine to a horse-drawn carriage or install a hydrogen fuel cell in it? I cannot believe something mathematically so different can be made compatible. Therefore, the chains that people are currently obsessed with will be left behind by the times and fade away. The heap of so-called NFTs—little more than worthless receipts—sitting atop them will follow suit.
